WEB-FOLDING MACHINE.

Specification of Letters Patent.

Application filed July 19, 1911.

To all whom it may can 061%:

Be it known that I, HOWARD M. BARBER, a citizen of the United States, and resident of Stonington, in the county of New London and State of Connecticut, have invented new and useful Improvements in Web-Folding Machines, of which the following is a specification.

This invention relates to improvements in the conditions very rarely exist where both webs require the same tension to feed them through the machine in register.

The object of this invention. is to feed each of the narrow webs after it has passed the turner down through the machine to the transverse cutters in a separate path thus rendering it easy to adjust the feed of each narrow web so that all of the webs will be brought to the transverse cutters in register.

A. practical embodiment of this invention is represented in the accompanying drawings, in which- Figure 1 is a vertical longitudinal section through so much of a web folding machine as will give a clear understanding of the invention, Fig. 2 is a detail section taken in the plane of the line AA of Fig. 1, and Fig. 3 is a detail section taken in the plane of the line BB of Fig. 1.

Upper and lower broad webs 1 and 2 are fed from a press or presses, not shown, around adjusting rolls, 3, 4, and over the feed roll 5. From thence the associated upper and lower broad webs pass over the slitting roll 6 where they are separated into a plurality of narrow webs by the slitters 7. In the present instance, three of these slitters 7 are shown for dividing the two associated broad webs into four groups of narrow webs 1*, 2*, l** 23 3 13"? 2** Z=, d li t-3 2=l= I= l =l= Four single turners 8 are shown located adjacent to the slitting roll 6.

As the associated narrow webs leave the points of the turners 8 they pass between the pairs of feed rolls 9, 10, and from thence around single feed rolls 11. The pairs of superposed narrow webs are then separated and led by separate paths down to the pair of feed rolls 12, 13, where they are all associated together and fed to the pair of transverse rotary" cutters 14, 15. The associated group of sheets may then be passed through suitable folding mechanism, such, for instance, as folding cylinders 16, 17 and may be transferred to different points such as endless delivery carriers 18, 19, by the cylinders 20, and 21 and their coacting parts.

Between the feed rolls 11 and the pair of feed rolls 12, 13, the narrow web 1* passes over the intermediate rolls 22, 23, 24; the

.narrow web 2 passes over the intermediate rolls 25, 26, 27, 28; the narrow web 1** over the rolls 29, 30, 31, 32, 28; the narrow web 2* over the rolls 33, 34, 35, 32, 28; over the rolls 36, 37 38, 39, 40, 41; the narrow web over the rolls 36, 37, 42, 43, 40, 41; the narrow web 1**** over the rolls 44, 45, 46, 41; and the narrow web 2**** over the rolls 47, 48, 49. Any of these individual feed rolls may be individually adjusted in any well known or approved manner, as for instance as shown in United States Letters Patent to Cundall, No. 1,000,670 dated August 15, 1911, for imparting the desired speed to its individual narrow web so that all of the narrow webs passing through their separate paths may be fed at the desired speed to bring them into proper register before subjecting them to the cutting and folding operations.

It is to be understood that the several rolls, cutters, and cylinders are suitably driven through trains of gears such, for instance, as those shown in the accompanying drawings, a specific description of which is not thought necessary herein.

What I claim is 1. In a machine of the character described, a turner around which two superposed webs are passed, a cutting and folding mechanism and adjustable means for feeding each of the webs through a separate path from the turner to the cutting and folding mechanism at the desired speed to bring the said webs together in register.

2. In a machine of the character described, a turner around which two superposed webs are passed, web feeding rolls adjacent to the turner, a cutting and folding Copies of this patent may be obtained for mechanism, web feed rolls adjacent thereto and adjustable means for feeding each of the webs through a. separate path from the first-mentioned feed rolls to the secondmentioned feed rolls at the desired speed to bring the said webs together in register.

In a machine of the character described, means for slitting two superposed broad webs into a plurality of superposed narrow webs, a turner for each pair of narrow webs, a common cutting and folding mechanism and adjustable means for feeding each of the narrow webs through a separate path from the turners to the cutting and folding mechanism at the desired speed to bring the said webs together in register.

l. In a machine of the character described, means for slitting two superposed broad webs into a plurality of superposed narrow webs, a turner foreach group of narrow webs, web feed rolls adjacent to the turners, a common cutting and folding mechanism, web feed rolls adjacent thereto and adjustable means for feeding each of the narrow webs through a separate path from the first-mentioned feed rolls to the last-meiitioned' feed rolls at the desired speed to bring the said webs together in register.

In testimony, that I claim the foregoing as my invention, I have signed my name in presence of two witnesses, this seventeenth day of July A. D. 1911. HOWVARD M. BARBER.
